SHUTTLE-SHIELD FRAME FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Aug. 13,1912.

Application filed February 4, 1911, Serial No. 606,509. Renewed June 24, 1912. Serial No. 705,642.

To all whom it may concern:

Be it known that I, JOHN A. Roi-FIN, 'a citizen of the United States of America, residing in the borough of Manhattan, city of New York, county and State of New York, have invented certain new and useful Improvements in Shuttle-Shield Frames for Type-WVriters, of which the following is a specification.

This invention relates to shuttle-shield frames for typewriters, and more particularly, to such as applied to a machine of the well known Hammond type.

In the use of the frames hitherto employed, great difficulty was often encountered in disengaging the frames from their holding parts and in the replacing of shuttle-shields, which by the unequal movement of the sides of the frame were bent and the shuttle-shield injured.

The object OfitlliS invention is to provide a simple construction by which it is possible to easily shift the shuttle-shield frame from its operative position to its inoperative position, and in this position hold the shuttleshield frame in raised position for inserting new ribbons and cleaning the shields and for replacing broken shuttleshields.

A further object is to positively hold or lock the frame in operative position. this end I have provided a shuttle-shield frame pivoted in a bracket secured to the front part of the top face of the typewriter frame, and the frame extending around the typewriter shuttle and anvil and holding the shuttle-shield between the hammer and the shuttle, said bracket being cut away to enable the frame to be shifted therein and also so as to form a shoulder for holding the shuttle-shield frame in raised position. Locking means are also provided to hold the frame in position during the operation of the machine.

In the accompanying drawings, Figure 1 in a plan-view of the invention as embodied in an approved form of the Hammond typewriter Fig. 2 is a front-elevation of the same, Fig. 3 is a cross-sectional view showing the new shield frame in side elevation,

in upward position in full lines and in operative positlon in dotted lines, Fig. 4 is an shown in dotted lines in different positions,

and Fig. 6 is a sectional view of the typewriter frame showing the shield frame supporting bracket in end elevation, part of the shield-frame being shown in dotted lines in two positions.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring more particularly to the drawings, the anvil 10. the shuttle 11, the hammer 12 and the ribbon-spools 13 are of the ordinary construction and arrangement. The ribbon passes from the spools between the shuttle and hammer by way of guidefingers 14 and 15 arranged in pairs onarms 16 which are suitably secured to the frame part 17 of the typewriter. The shuttleshield 18 is carried in the usual manner by a frame 19 comprising arms of curved form to embrace the anvil 10, being united at the front of the machine and ivoted by a bracket 20 on the ring-or rounding the anvil. The shield-frame 19 is bent at its front'part to form a manipulating finger 19. The shuttle-shield is provided with an opening or openings in which the hammer 12 strikes, as is well known. Lugs or fingers 25 are provided on the arm 16 whichserve to elevate the ribbon to permit writing in another color, the frame being held thereunder in the position of the solid lines in Figs. 1 and 2. These parts with the exception of the novel bracket 20 shown in the drawings, are all well known.

In order to hold the shield-frame in operative osition a locking lug 26 is provided slidab y mounted in a slot 27 in the ring 21 and supported on a link 28 pivoted as at 29 ame 21 surthe dotted lines v I 33 of the bracket 20. This holds the frame shield-frame 19.

.shuttleshields to be renewed in case they whereupon it is lowered to its .may be varied withou; departing from the spirit and scope of lug 26 is moved to the position of dotted lines of Fig. 1, thus permitting the frame. 19 to be moved or shifted laterally so as to occupy the initial position shown in the dotted lines, by which rectilinear movement it clears the lugs 25 from which'initial; position it may be moved upwardly to the position shown by the full lines of Fig. 3. The frame-l9 is then moved farther in the bracket 20 laterally of the initial position to the extreme left-hand position shown by of Fig. 5, in whiehposition the straight part- 30 of the frame 19 rests upon the shoulder 31 formed by the recess 32 in the right hand bearing sleeve 19 in the inoperative position shown in Fig. 3, in full lines, which position enables the may be worn out or broken, the hooked ends 35 of the shuttle-shield being easily slipped off from the downwardly bent end :26 of the When the frame is desired to be again lowered,-it is shifted laterally, now in opposite direction to the former shifting so as to disengage from the recess ofthe bracket,

initial position, when the operation of the locking-lug by its movement moves the frame from its initial position back to its operative position and holds it there.

My invention therefore consists of the laterally shiftable shuttle-shield frame, which is normallyheld in position against lateral and upward movemenfland further in the means for locking it in position.

e arrangement and details of construction of the herein described improvementthe invention as defined in the appended claims.

Having thus described claim as new and desire to atent:

1. In a typewriter of the Hammond type,

the combinationof a shuttle-shield frame my invention, I secure by Letters its operative position.

2 In a-typewriter, pivotally operative I movable shuttle shield frame capable of latin upward position.

,3. In a typewriter, the combination of a pivoted shuttle-shield frame, capable of lat eral movement and means adapted to engage saidframe, move it from its initial to its operative position and hold it there.

In a typewriter, a shield frame, means i holding the shield frame in operative position when in one position of its rectilinear movement.

5. In a typewriter, the combination of a shield frame, a bracket for holding said frame and permitting rectilinear movement and. pivotal movement of the same, means for holding said framein inoperative position when it is in one position of its rectilinear movement, and means moving said frame from its initial position into' operative position and holding it there.

6. In a typewriter, a frame with a slot, undercut lugs mounted on said typewriter frame, a shield frame adapted to be placed under said lugs when in one position of its rectilinear movement and capable of rectilinear movement in order to be releasedtherefrom, and a locking lug movable in the slot to be placed under said lugs when in one position of its rectilinear movement, a link pivoted to the under face of said typewriter frame and a locking lug movable in the slot of the frame and said shoulder frame to hold the same under the undercut lugs.

, 8. In a typewriter, the combination of a bracket having a bearing sleeve, said bearing sleeve having-a cutout recess at its 11 er part forminga shoulder and a shield frame having a straight part received in said hearing sleeve whereby said shield frame is adapted for rectilinear and pivotal move ment therein and having another part adapted to engage the recess for holding the frame therein.

9. In a typewriter, a pivotally movable shuttle shield frame, the entire frame being; capable of lateral movement from its operative position to a shifted position for re-' easing it, and capable of upward movement while in shifted position.

0. In a typewriter, a pivotally movable shuttle-shield frame, the entire frame being capable of lateral movement from its operative position to a shifted position for releasing it, and capable of upward movement while in shifted position, means for holding it in upward position and means for looking it in its operative posit-ion.

a typewriter. a pivotally movable capable of lateral movement from its operative position to a shifted position for releasas my invention, I have signed my name in ing it, and capable of upward movement presence of two subscribing witnesses. While 1n shlfted posltion, and means shift- 4 ing the frame from its shifted position to RUFFIN' operative position and holding it in that Witnesses: position. H. GonPnL,

In testimony that I claim the foregoing L. M. DORMAN.
